Ibuki substrate particle size

[snox]

Is the ibuki substrate particle size stated on there products true . they state 4:5 to 5 mm which is perfect but thought I would ask others about there experience with it .
I ask because just brought some akadama here in the UK sold as 2-5 mm and seems there are 5 mm particles but most of it is 2mm which is no good to me .

Do not know the Ibuki brand but experience with other substrate grading is that the particle size is 'rough' and that's the same with gravel, sand, perlite and all other substrates.
Machines are used to grade the particle size. How efficient that is depends on soil moisture and what's actually in the soil when it goes into the machine. Some batches will have more of the smaller size, some more of the larger. Some may even have more under size particles that have escaped the smaller screens and ended up in the next size range.
Hopefully, someone can help with another brand with better grading consistency but I'd still expect some variation.

Not sure I understand the question.

- Is the ibuki substrate sifted to size: Yes
- Is the size on the website correct or do I get grains that are much smaller: In principle you can expect the grains to be roughly the size indicated
- Do I get loads of particles smaller than the range? No, if you want the smallers grains you get their 2.53mm grains

Naturally, between sifting, packaging, storing and transporting you will get grain reduction. And not all sifting is perfect. But they give a range so you know what you get.
The pictures are pictures of the stuff they send, in my experience.

Haha never been good at explaining myself with the written word . It was your second point about roughly being the same size . I get that via transport there might some breakdown/reduce .
Guess best order as there statement of 4-5 mm seems very accurate .
Thanks
